Those graphs/tools are being used by the guys/gals looking to do profiles for the HDR content to try to get better dynamic out of their displays. A lot of them are using displays with very low nits (projectors some with 50 nits max) so they're trying to find ways to squeeze out every last bit of detail they can. All of that is just people waiting on the next step in the HDR tonemapping progression while madshi pushes out a new official build. It's making them happy, but, you can safely ignore it for now as when madshi is at a "final solution" none of that should be necessary.

Edit: After reading brazen1's post on FSE, I would like to do more testing. But have to say did not notice any big difference in PQ after FSE was enabled. Maybe I was focused too much on the stuttering. Last edited by austinminton; 29th November 2018 at 01:00. |

I see no difference in FSE and FS windowed. Even showrendersteps has the same steps in both. I do get stuttering when switching from FSE to FS windowed but that is related to the queues flushing out. Everything goes back to normal once queues are full. GPU load is about the same in both as well.
Quite happy with FSE on my 2080 ti. |

Yesterday I've done the following test: Hooked up my HTPC to my LG OLED 65C8 tv. When connected to this display into NVIDIA control panel (I've a GTX970) the option to send RGB@24hz 12bpc appears. When the htpc was hooked up with Sony VW520ES projector the nvidia control panel only give me the possibility to connect me in RGB@24hz 8bpc.... I imagine that's because the sony projector has only hdmi ports @9Gbps. Anyway first I've set nvidia control panel to work in RGB@24hz 8bpc. Set Madvr to see the display only 8bit compatible and activated ordered dithering. The bandings that normally I can see on the Sony projector are vanished on Lg tv. So this is the prove that Madvr works well in 8bit mode and what I've seen was only a problem of my sony pj with RGB signal input. After this test I've set nvidia control panel to RGB@24hz 12bpc. I've setted Madvr to ask to the display the bit depth. Leaved ordered dithering. When I've played my UHD HDR10 files I've seen (in full exclusive mode) madvr works in 10bit domain. I've tested my reference scenes and bandings are not there. Sincerely I can't see any difference between my chain @8bit. So my question is: With displays that accepts RGB@24hz 12bpc ... What is the best theorical setting? is it better to set nvidia cp and madvr @8bit? or it's better to set the nividia cp@ 12bpc and madvr@10bit? let me know. Thanks |

It should work well at madVR 10-bit and Nvidia 12-bit RGB.
Did you compare straight HDR passthrough?

Hi guys,
first post first question I set up madvr a while ago and it was working fine for me. not sure what I`ve done to my settings yet but madvr is not autmatically switching resolution on my 4k display. I have added all 2160p resolutions in the madvr and made sure the settings for auto switching are enabled in madvr. but for some reason it does not switch the screenmodes automatically... it just to work fine. not sure which setting I might have screwed up thanks for help |

https://forums.geforce.com/default/t...24386/#5924386 It is quite scary how much they break things in drivers nowadays, I gave up downloading them, there are no gains if you do not play games, and indeed more chance of new problems that should not happen. |

just been having a look again at how MADVR deals with really poorly mastered and heavily compressed material. This clip is horrific on OLED but what is odd is that the only option that does anything at all to mask some of the problems is the debanding filter, random noise and compression artefcts do nothing at all even on 14 with the macro blocking which makes me wonder what these are actually doing, they just seems to blur the entire screen for me.
debanding on high does a reasonable job of masking the major issues that a crush doesnt fix but damages the over all PQ shaprness quite badly. Does anyone use reduce random noise / compression artefacts, if not then maybe we could scrap these and have something that specifically targets dark low IRE areas and shadow like what was suggested a couple of pages back. I really think this should be given some dev time by MADSHI when he's got HDR up to scratch as more people are getting OLEDs and there is just so much poorly mastered material out there. clip: https://1drv.ms/v/s!AgvFafeelEBigP96N4PQZzBs4iPcfg I know you cant polish a turd but MADSHI could maybe spray some MADVR fairy dust on it and make it smell nice.

It could be great if there was a high quality noise reduction + option to apply it on near black zones in a scene...

Hi because I am still on a gtx 960 4g which delivers a great picture via madvr on Lg oled and after tweaking some settings (thx to the feedback of the community) and match refresh rates in madvr it is even more hard to think about a gpu upgrade.
My Favorit will be a gtx 1070ti but I am also looking into the amd section rx 580 up to vega 64 Could be possible but I think more than a vega 56 won't be possible without changing the power supply. So my question is can some rx 580 user tell me what the highest settings are possible to use within madvr for upscaling DVD and blu-ray to 4k output. I am using an LG oled which is calibrated and 3d lut in madvr. Price of the rx 580 is nowadays amazing and for the 1070 ti I was to slow to catch them at a good offer. I want also the gpu upgrade not only for madvr but I do some video editing and could also get some benefits on a stronger gpu. Brgds Ampa Last edited by Ampallang; 1st December 2018 at 10:01. |

Even given the low prices for the Rx580 now you'd probably still be better off with a 1060 6GB for madVR, if you're doing more than that then sure the RX580 is more worthy of consideration.

I've recently bought a G-Sync monitor and now have a small problem and hope that someone can help me.
Although I'm not using fullscreen exclusive mode I get a short black flicker when I switch between windowed and fullscreen windowed mode. It seems like my monitor is switching G-Sync off when entering fullscreen windowed and switching it on again when leaving it - at least that's what its OSD says. This is especially annoying since it also happens when the seek bar is shown or hidden. I'm using MPC-BE as player, but the problem does not happen with EVR-CP, so it seems to be madVR specific. I've already configured the Nvidia driver to not use G-Sync for MPC-BE and this also had an effect (madVR shows the "normal" refresh rates - before they were way different), but doesn't seem to be enough? My madVR settings: * Fullscreen exclusive mode off * D3D11 for presentation * Native D3D11 decoding with LAV My Nvidia settings: * G-Sync globally on for fullscreen and windowed modes (I need this for games - it seems like it's not possible to globally disable it and just enable it for specific games) * Added MPC-BE for custom application settings and configured it to use fixed refresh rates instead of G-Sync Anyone an idea how to fix this? In other words, how do I completely disable G-Sync for MPC-BE/madVR while keeping it active for games? Last edited by cremor; 1st December 2018 at 13:55. |

Curious about how future Dolby Vision could work for HTPCs.
As far as I understand things, I think Profile 5 support is more likely to come. That "fuses" the two layers used on BluRay UHD in a single video stream, for the TV to interpret. That's what Apple TV 4K uses, if I'm not mistaken. We currently can rip BD UHD and keep Dolby Vision, but it's Profile 4. I guess that would require a change in mkvtoolnix to have mkv handle two video streams concurrently. But then something would need to put the two streams together, right? My question is: at what stage would this "fusion" need to happen? Decoder? Renderer? So, basically, would it be a job for LAV or madVR? |
